Abstract

A seat for a passenger compartment, for example a vehicle passenger compartment. The seat has a backrest that includes a heating device for heating the space behind the backrest. The heating device includes, from front to back of the backrest, an insulating layer which is a foam, a heating layer, and an outer layer which forms the back of the backrest. The assembly of the insulating layer and the heating layer is achieved by compression on at least their peripheries.

Claims

1. Seat backrest comprising a heating device for heating a space behind the backrest, wherein said heating device comprises, from a front of said backrest to a back of said backrest, an insulating layer which is a foam, a heating layer, and an outer layer which forms the back of said backrest, said insulating layer and said heating layer being assembled together by compression on at least their peripheries.

2. Seat backrest according to claim 1, wherein said heating layer is in contact with said insulating layer over an entire surface of said heating layer facing said insulating layer, and wherein said heating layer is in contact with said outer layer over an entire surface of said heating layer facing said outer layer.

3. Seat backrest according to claim 1, wherein said heating layer is separated from said outer layer by a first air layer, and wherein said outer layer has holes for communication between said first air layer and the space behind said backrest, said heating layer and said outer layer being in contact with each other on their peripheries.

4. Seat backrest according to claim 3, wherein said heating layer is separated from said insulating layer by a second air layer, said heating layer and said insulating layer being in contact on their peripheries.

5. Seat backrest according to claim 4, wherein said heating device further comprises a radiation-reflective layer, in contact with said insulating layer and between said second air layer and said insulating layer.

6. Method for manufacturing a heating backrest of a seat, comprising the following steps:

(a) providing an insulating layer which is a foam, a heating layer, and an outer layer intended for forming the back of said backrest;

(b) positioning said layers, from front to back of said backrest, as follows;

said insulating layer, then said heating layer, then said outer layer; and

(c) assembling said layers, wherein said insulating layer and said heating layer are assembled by compression on at least their peripheries.

7. Method for manufacturing a seat backrest according to claim 6, wherein, before step (a), said insulating layer is created by spraying a foam on a plastic film.

8. Method for manufacturing a seat backrest according to claim 6, wherein said heating layer and said outer layer are assembled by compression on at least their peripheries.

9. Method for manufacturing a seat backrest according to claim 6, wherein said heating layer and said outer layer are assembled by means other than compression on at least their peripheries.

10. Method for manufacturing a seat backrest according to claim 6, wherein, in step (c), said layers are assembled over their entire surfaces so that said heating layer is in contact with said insulating layer over an entire surface of said heating layer facing said insulating layer, and wherein said heating layer is in contact with said outer layer over an entire surface of said heating layer facing said outer layer.
